Adaptive personalized thermal comfort prediction device and method based on human body similarity

Abstract

The invention discloses an adaptive personalized thermal comfort prediction device and method based on human body similarity, and relates to the field of human body thermal comfort detection. The device comprises a data acquisition unit, a data adaptive adjustment unit, a personalized thermal comfort prediction model construction unit and an environment control unit. The method comprises the stepsof collecting a large amount of user data to form a data set; calculating thermal perception similarity between a target user and other users in the data set; re-sampling the basic data set accordingto the thermal perception similarity to form a new data set; establishing a personalized thermal comfort prediction model according to the new data set; colleting related data of the target user in real time, calculating thermal comfort data according to the model, and generating an air conditioner control signal; and sending the air conditioner control signal to regulate and control the air conditioner. According to the method, the preference of the target user to a thermal environment can be effectively captured, so that the established thermal comfort model has personalized characteristics, the prediction accuracy is improved, and the method has practical value.

Description

technical field [0001] The invention relates to the field of human body thermal comfort detection, in particular to a device and method for adaptive and personalized thermal comfort prediction based on human body similarity. Background technique [0002] With the development of society and economic progress, people's requirements for environmental comfort are gradually increasing. Modern people usually spend more than 80% of their time indoors, so the indoor thermal environment will have a huge impact on people's physical and mental health, comfort and work efficiency. Maintaining a good and comfortable indoor thermal environment is crucial to ensuring that people Normal work, study and life are of great significance. [0003] The evaluation and prediction of the thermal comfort state of the human body has always been a very important research content in the thermal comfort research. Whether the thermal comfort state of the human body can be accurately evaluated is the basi...
